Application filed July 16, 1917, Serial No. 180,853. Renewed April 8, 1920.. Serial No. 372,318.

To all whom it may concern Be it known that I, TURNER T. Porn, a

citizen of theUnited States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements. in vapor zing Attachments, of which the following is a specification.

This invention relates to new and useful improvements in a vaporizing attachment for printing presses.

The object of the invention is to provide an attachment of the character described by means of which vapor may be applied to ened fromany cause, it often tears in two in the process of printing, thus causing delay. Furthermore, the friction caused by the dry sheet of paper passing over the metallic rolls of the press and coming into contact with the other metallic parts thereof at a high rate of speed generates static electricity which tends to cause the paper to adhere to the metal, thus making a considerable pull on the paper necessary in order to move it through the'press at the required rate of speed, the resistance some times causing the paper to tear in two. If the paper is slightly moistened it is not so liable to tear and the friction of the damp paper does not generate electricity and for that reason the attachment herein described has been provided for the purpose of applying steam to the paper just after it leaves the rolls and before it enters the press.

Furthermore in shipping paper rolls, the ends of the roll sometimes become dented or otherwise mutilated and in unrolling' the paper the edges are thereby caused to adhere together, thus causing the paper to tear in two. In order to cause the edges of the plies to separate at the ends of the roll, the device has been arranged to apply steam to said ends which softens the paper and causes the plies to separate so that the paper will readily unwind from the roll without resistance.

A further feature of the invention resides in the provision of an attachment of the characterdescribed whereby steam may be applied to the ends of one or any number of rolls, as well as to the paper being unwound from the rolls.

In the application of steam to the paper passing through thepress, it is essential that steam only be applied, not water inliquid form, as the latter would weaken the paper and cause it to tear. For that reason, I have provided an attachment of the character described whereby all condensed water will be drained out, leaving only the steam in a state of vapor to be applied to the paper.

With the above and other objects in view, the invention has particular relation to certain novelfeatures of construction, arrange ment of parts and use, anexample of which s given in this specification and illustrated in the accompanying drawings, wherein:

Figure 1 is a front elevation of the device as applied to a printing press.

Fig. 2 is an enlarged fragmentary front elevation thereof. i

Fig. 3 is a side view showing the rolls from which the paper has been partially unwound, and

Fig. 4 is an enlarged fragmentary side elevation thereof.

Referring now more particularly to the drawings wherein like numerals of reference deslgnate similar parts in each of the figures, the numerals 1, 1, refer to the side members of the rear end'of a printing press wherein a plurality of paper rolls 2 are rotatably mounted, the number of rolls depending upon' the character of the press. The paper is unwound from these rolls forming sheets 8, 3, 3, each sheet passing around the respective idler rollers 4 and 5 before entering the press proper. The numeral 6 refers to a steam line which is controlled by the valve 7 and from which leads the two steam pipes 8, 8, arranged on opposite sides of the press and connectedby the nozzles 9, 9, 9, said last mentioned nozzles passing under the respective sheets 3 and each of these nozzles has a row of perforations 10 along its upper side through which steam is forced against the corresponding an even distribution of steam through said nozzles. At the ends of the rolls are the nozzle pipes 12, 12, 12, which are connected with the nozzles 10 and which lead to and connect with the respective drain pipes 13. Opposite the ends of the rolls these pipes 12 are provided with perforations 14 through which steam is discharged against the ends of the roll and in case any water should condense and collect in the nozzles 9, it will be drained off through the pipes 12 into the drain pipes 13, thus preventing any water in its liquid form from beingforced against the paper. The drain pipe 13 is provided with traps 15 between the pipes 12 and the drain pipes converge together into a common pipe 16 provided with the trap 17 These traps prevent any back pressure of steam as only a low pressure of steam is necessary for the operation of this device so that steam may be applied to either one of the rolls or to all of them at the same time if desired. There is only a small amount of water which condenses in the nozzles and drains through the pipes 12 and never enough to fill them up to the perforations 1 1 so that only steam, and no water, is discharged against the ends of the roll.

T he steam is thus applied to the end of each roll from the center to the circumference, moistening the entire end of the roll as it rotates and is also applied to the unwound paper from edge to edge as it'passes through the press, thus moistening and toughening the paper, preventing the tearing thereof and also minimizing the generation of static electricity caused by the friction of the paper as it passes through the press.

WVhat I claim is:

1. An attachment for printing presses including a steam line, atransverse nozzle connected to said line provided with steam outlets and arranged to project steam against the sheet of paper passing through the press and a nozzle pipe connected to said nozzle provided with steam outlets and arranged to project steam against the end of the roll from which said paper is unwound.

2. An attachment for printing presses including a steam line, a nozzle connected to said line at each end and provided with steam outlets and arranged to project steam against the paper being unwound from a roll, means for controlling the entrance of steam into said nozzle at each end, a nozzle pipe leading from said nozzle and arranged at each end of said roll, said nozzle pipe being provided with steam outlets through which steam is projected against the ends of the roll.

3. An attachment for printing presses ini,s41,76o

cluding a steam line, a pair of steam pipes leading therefrom, a nozzle communicating with each of said pipes, a valve controlling the entrance of steam from each pipe into the nozzle, said nozzle being provided with steam outlets through which steam is projected against the paper being unwound from the roll in the press, a pair of drain pipes and nozzle pipes leading from said nozzle at each end and communicating with the corresponding drain pipes, said nozzle pipes being provided with steam outlets and arranged to project steam through said outlets against the ends of the corresponding paper rolls.

)4. An attachment for printing presses including a steam line, a pair of steam pipes leading therefrom, a plurality of nozzles communicating with each of said pipes, a valve controlling the entrance of steam from each pipe into the nozzle, said nozzles being provided with steam outlets through which steam is projected against the paper being unwound from the rolls in the press, a pair of drain pipes and nozzle pipes leading from said nozzles at each end and communicating with the corresponding drain pipes, said nozzle pipes being provided with steam outlets and arranged to project steam through said outlets against the ends of the corresponding paper rolls and traps in said drain pipes between said nozzle pipes.

0. An attachment for printing presses including a steam line, a transverse nozzle' connected to said line provided with steam outlets and arranged to project steam against the sheet of paper passing through the press and a nozzle pipe provided with a nozzle arranged to project steam against the end of the roll from which said paper is unwound.

p 6. An attachment for printing presses including a vapor conduit arranged to project vapor against the sheet of paper passing through the press and means arranged to project vapor against the ends of the roll from which said paper is unwound.

7. An attachment for printing presses including a vapor conduit arranged to project vapor against the sheet of paper passing through the press, and means arranged to project vapor against an 'edge of the paper while in a roll before'being unwound.

In testimony whereof 1 have signed my name to this specification in the presence of two subscribing witnesses.
